Adjustment of the Hygrometer
Initial adjustment of the hygrometer is not necessary. However, to maintain
accuracy, it is recommended that hygrometers be kept in permanently low
humidity areas (i.e., central heating/air conditioning, etc.) wrapped in a damp
cloth for 24 hours to reactivate “lazy” dried out coils. After the 24 hour period,
the scale should read approximately 95%. Repeat this procedure every three
to four months for best performance.
Hygrometer Specifications:
Range: 20-90% RH
